At 24 I was working on my own company focused on websites and working around 24/30 hours in Sales. Was I happy? Quite yes. Was I satisfied with my salary and job? No.
I did enjoy the sales time - it helped me a whole lot in gaining knowledge and practical skills of selling and talking. I had to go door-to-door and walk up to people on the streets. Only it wasn't what I really wanted to end with. I lost the joy in coding while partying and bringing in quite some money for my age and hours I put in the work.
This year (almost 2 years later, as I'm moving on to my 26th year on the 28th) I've started following an education of Computer Science and after a bumpy first start I'm enjoying coding again - while still maintaining a nice average of what I earned before this.
